- the upper part holding tool 11 and the lower part holding tool 12 respectively comprise a moulded body made of a resin material, the upper part holding tool 11 being formed as an approximately square plate shape which is formed with cut-out angled parts having a curved surface, and the lower part holding tool 12 being formed as an approximately rectangular plate shape which is formed with cut-out angled parts having a curved surface.
- circular holding holes 11 a , 11 b are formed in both side portions of the upper part holding tool 11 so as to be a prescribed distance apart with the centre point of the upper part holding tool 11 lying between them, and circular holding holes 12 a , 12 b are formed in both side portions along the longitudinal direction of the lower part holding tool 12 with the same space between them as that between the holding holes 11 a , 11 b.
- the insertion puncture needle 13 is configured by a stainless steel cylindrical body inside which an insertion hole 13 a (see FIGS. 6 to 9 ) is formed, and a gripping part 17 made of resin is attached to its base end part (upper end part).
- the upper part of said gripping part 17 is formed as a cylindrical shape with a large diameter while the lower part is formed as a cylindrical shape with a small diameter, and a guide hole 17 a which links in communication with the insertion hole 13 a is formed inside it.
- the upper part of said guide hole 17 a is formed with a large diameter while the lower part is formed with a small diameter so as to follow the outer peripheral surface of the gripping part 17 , and by virtue of this the suturing thread 16 is easily inserted inside the insertion hole 13 a of the insertion puncture needle 13 from the top of the gripping part 17 .
- the tip end part (lower end part) of the insertion puncture needle 13 has an oblique section, and is formed with an opening part 13 b which is visible from the lateral direction (the retrieval puncture needle 14 side). Then, said insertion puncture needle 13 is inserted and held in the holding hole 11 a of the upper part holding tool 11 and the holding hole 12 a of the lower part holding tool 12 in a state in which the opening part 13 b is oriented in the direction of the central part of the upper part holding tool 11 and the lower part holding tool 12 .
- the upper part holding tool 11 holds the portion in the vicinity of the base end part of the insertion puncture needle 13
- the lower part holding tool 12 holds the portion which is somewhat further towards the lower side than the base end part of the insertion puncture needle 13 , with a gap maintained between said tool and the upper part holding tool 11 .
- the attachment position of the lower part holding tool 12 in this case with respect to the insertion puncture needle 13 is appropriately set in accordance with the degree of protrusion of the portion of the insertion puncture needle 13 further to the lower side than the lower part holding tool 12 .
- the retrieval puncture needle 14 is configured by a cylindrical body made of stainless steel inside which an insertion hole 14 a is formed in the same way as for the insertion puncture needle 13 , and a gripping part 18 made of resin is attached to the base end part.
- the upper part of said gripping part 18 is formed as a columnar shape with a large diameter while the lower part is formed as a columnar shape with a small diameter, and a penetration hole 18 a which links in communication with the central part of the insertion hole 14 a which runs in the axial direction thereof is formed to pass through vertically.
- an engagement hole 18 b which passes from the inside to the outside is provided at the upper part portion on the peripheral surface of the gripping part 18 , as shown in FIGS. 3 to 5 .
- the tip end part of the retrieval puncture needle 14 has an oblique section, and is formed with an opening part 14 b which is visible from the lateral direction (the insertion puncture needle 13 side).
- the linear gripping member 15 is configured by a linear insertion rod 15 a which is configured by a narrow rod made of stainless steel, and a gripping part 15 b comprising a fine wire extending from the tip end part of the insertion rod 15 a and forking, on which wire a bent part is formed at the respective tip end parts.
- the linear gripping member 15 can be inserted inside the insertion hole 14 a of the retrieval puncture needle 14 , and the gripping part 15 b extends from the tip end part of the insertion rod 15 a so as to spread with a gap between the tip end parts in the direction orthogonal to the insertion rod 15 a .
- the gripping part 15 b is deformable, and when it is positioned inside the insertion hole 14 a of the retrieval puncture needle 14 it extends to become approximately linear, as shown in FIGS. 6 to 9 , and when it is protruding from the opening part 14 b of the retrieval puncture needle 14 , it extends orthogonally from the insertion rod 15 a to spread to the insertion puncture needle 13 side, as shown in FIGS. 7 and 8 .
- a columnar gripping part 19 which acts as the retracting operating member of the present invention is mounted on the upper end part of the insertion rod 15 a on the linear gripping member 15 . Furthermore, an expandable engaging part 21 is attached to the portion in the vicinity of the gripping part 19 on the insertion rod 15 a , and a coil spring 22 which covers the outer peripheral surface of the upper part portion of the insertion rod 15 a is fixed to the lower end surface of the expandable engagement part 21 . The lower end part of said coil spring 22 is supported by the bottom part of the gripping part 18 .
- the expandable engagement part 21 is configured by a flexible resin member, with a recess part 23 a being formed on one side on the upper surface and also a recess part 23 b being formed on the other side on the lower surface; the configuration is such that said expandable engagement part can expand or contract in the longitudinal direction (the left-right direction in FIGS. 3 to 5 ) by the application of a prescribed force. Furthermore, the lower surface of an end part 24 on one side of the expandable engagement part 21 is formed with an inclined surface 24 a . Consequently, when the coil spring 22 is contracted by the downwards pressure (downwards movement of the insertion rod 15 a ) of the expandable engagement part 21 from the situation shown in FIG. 3 , the expandable engagement part 21 contracts and enters the penetration hole 18 a of the gripping part 18 while the inclined surface 24 a and the other end part are pushed against the inner peripheral surface of the penetration hole 18 a , as shown in FIG. 4 .
- the expandable engagement part 21 is first of all pulled upwards of the gripping part 18 by means of the elasticity of the coil spring 22 , and a state is achieved in which the upper part portion of the insertion rod 15 a is made to protrude upwards of the gripping part 18 .
- the linear gripping member 15 is pulled upwards and is positioned inside the insertion hole 14 a of the retrieval puncture needle 14 .
- the medical suturing tool 10 is pushed into the surface of the patient's skin in the abdomen part, and, as shown in FIG.
- FIGS. 6 to 9 which are used for the description given below are drawings showing the medical suturing tool 10 schematically, and the sizes etc. of all the elements are different from those of the medical suturing tool 10 shown in FIGS. 1 and 2 .
- the insertion puncture needle 13 and the retrieval puncture needle 14 are pushed in until the lower part holding tool 12 reaches the surface of the skin of the abdominal wall A, and the opening parts 13 b , 14 b are positioned inside the gastric wall B.
- the gripping part 19 is pushed downwards to push the upper part portion of the insertion rod 15 a inside the insertion hole 14 a of the retrieval puncture needle 14 .
- the gripping part 15 b of the linear gripping member 15 is sent outwards of the retrieval puncture needle 14 from the opening part 14 b , it bends in a horizontal direction and also forks with a gap between the tip end parts, extending to the insertion puncture needle 13 side, and the situation shown in FIG. 7 is achieved.
- the suturing thread 16 is inserted inside the insertion hole 13 a of the insertion puncture needle 13 from the guide hole 17 a of the gripping part 17 .
- the tip end part of the suturing thread 16 advances downwards inside the insertion hole 13 a , and extends outside and downwards from the opening part 13 b .
- the tip end part of the suturing thread 16 enters between the fork of the extended gripping part 15 b.
- the end part 24 of the expandable engagement part 21 is pushed inside the gripping part 18 and the engagement between the end part 24 and the engagement hole 18 b is released.
- the upper part portion of the insertion rod 15 a is raised so as to protrude upwards of the gripping part 18 due to the elasticity of the coil spring 22 , and the insertion rod 15 a together with the gripping part 15 b are also pulled upwards to achieve the situation shown in FIGS. 2 and 9 .
- the gripping part 15 b of the linear gripping member 15 deforms so as to narrow the forked portion, keeping the suturing thread 16 within said forked portion, and the tip end part of the suturing thread 16 enters the insertion hole 14 a of the retrieval puncture needle 14 in a state in which it is gripped by the gripping part 15 b.
- the elastic force of the coil spring 22 is set to be greater than the force by which the linear gripping member 15 is pulled by the suturing thread 16 when the medical suturing tool 10 is pulled out from the body of the patient. Consequently, when the medical suturing tool 10 is pulled out from the body of the patient, the linear gripping member 15 is prevented from returning inside the insertion hole 14 a of the retrieval puncture needle 14 , and the suturing thread 16 is held in an engaged state with the gripping part 15 b . As a result, stable suturing is possible.
- the insertion rod 15 a on the base end part side of the linear gripping member 15 is urged upwards by the coil spring 22 . Consequently, when the suturing thread 16 is gripped by the gripping part 15 b and is pulled inside the insertion hole 14 a of the retrieval puncture needle 14 , the insertion rod 15 a is pulled inside the insertion hole 14 a and it is possible to prevent the grip on the suturing thread 16 by the gripping part 15 b from being released. By virtue of this, it is possible to pull the retrieval puncture needle 14 and the insertion puncture needle 13 out from the patient's body without manually handling the linear gripping member 15 or the suturing thread 16 .
- the expandable engagement part 21 is provided on the insertion rod 15 a and also the engagement hole 18 b which can engage with the end part 24 of the expandable engagement part 21 is provided in the gripping part 18 , and therefore it is possible to fix the position of the gripping part 15 b when the gripping part 15 b of the linear gripping member 15 is protruding from the opening part 14 b of the retrieval puncture needle 14 .

Abstract
Description
- The present invention generally relates to a medical suturing tool for stitching a part to be sutured inside a patient's body.
- It is conventional practice to use a medical suturing tool in order to fixedly stitch an area to be sutured inside the body of a patient, and especially an area to be sutured consisting of skin and internal organs. For example, liquid food and drink such as liquid food diets and nutrients are supplied inside the stomach of people who have reduced ability to ingest food orally under their own power due to old age or illness, using a gastrostomy tube, but this gastrostomy tube is attached to the region of the patient's abdomen by the formation of a hole. In such cases, the abdominal wall and the gastric wall are fixed beforehand using a medical suturing tool in order to attach the gastrostomy tube properly (see Japanese Unexamined Patent Application Publication H5-161655, for example).
- These medical suturing tools are provided with two puncture needles which are arranged in parallel with a space maintained between them, and when suturing is performed these two puncture needles are first of all simultaneously pierced into the area to be sutured of the patient. Next, suturing thread is passed through one of the puncture needles, and also an inner needle to which a loop made of wire is joined at its tip end part is passed through the other puncture needle, and the inner needle is removed from the puncture needle in a state in which the suturing thread is gripped by the loop inside the patient's body. Then, after the two puncture needles have been removed from the patient, both side portions of the suturing thread which are protruding outside the patient's body are joined, whereby the suture is complete. Furthermore, the tip end part of the puncture needle in which the inner needle is inserted is formed with a curved part and its tip end opening is oriented horizontally, and because of this, when the inner needle is pushed inside the puncture needle, the loop extends in the horizontal direction and protrudes to the outside, and therefore the suturing thread is gripped.
- However, with conventional medical suturing tools, when the two puncture needles are pulled out from the patient, the two puncture needles must be handled together with the suturing thread while it is still being gripped by the loop, and therefore there are problems in that this handling is difficult and also the stability of the suturing is adversely affected.
- In one aspect of the present invention, a suture retrieval puncture needle for a medical suturing tool generally comprises an outer hollow needle member and an inner suture gripping element movable within the outer hollow needle member. The inner suture gripping element is deployable at least partially externally to the outer hollow needle member for retrieval of a suture. An operating member is provided at a proximal end of the suture retrieval puncture needle. The operating member is connected to the inner suture gripping element. Movement of the operating member relative to the outer hollow needle member causes the inner suture gripping element to move between a deployed position and a retracted position. The suture retrieval puncture needle further comprises a locking arrangement for releasably holding the operating member in a position relative to the outer hollow needle member in which the inner suture gripping element is in the deployed position.
- In another aspect, a medical suturing tool generally comprises a plurality of suture insertion puncture needles, and a suture retrieval puncture needle. A frame holds the plurality of suture insertion puncture needles and the suture retrieval puncture needle in a spaced apart relationship. The suture retrieval puncture needle comprises an outer hollow needle member and an inner suture gripping element movable within the outer hollow needle member. The inner suture gripping element is deployable at least partially externally to the outer hollow needle member for retrieval of a suture inserted into at least one of the suture insertion puncture needles.
- In yet another aspect, a medical suturing tool generally comprises a suture insertion puncture needle and a plurality of suture retrieval puncture needles. A frame holds the suture insertion puncture needles and the plurality of suture retrieval puncture needles in a spaced apart relationship. Each suture retrieval puncture needle comprises an outer hollow needle member and an inner suture gripping element movable within the outer hollow needle member. The inner suture gripping element is deployable at least partially externally to the outer hollow needle member for retrieval of a suture inserted into at least one of the suture insertion puncture needles.

expandable engagement part 21 is configured by a flexible resin member, with arecess part 23 a being formed on one side on the upper surface and also arecess part 23 b being formed on the other side on the lower surface; the configuration is such that said expandable engagement part can expand or contract in the longitudinal direction (the left-right direction in FIGS. 3 to 5) by the application of a prescribed force. Furthermore, the lower surface of anend part 24 on one side of theexpandable engagement part 21 is formed with aninclined surface 24 a. Consequently, when thecoil spring 22 is contracted by the downwards pressure (downwards movement of theinsertion rod 15 a) of theexpandable engagement part 21 from the situation shown inFIG. 3 , theexpandable engagement part 21 contracts and enters thepenetration hole 18 a of thegripping part 18 while theinclined surface 24 a and the other end part are pushed against the inner peripheral surface of thepenetration hole 18 a, as shown inFIG. 4 . - Then, when the
end part 24 of theexpandable engagement part 21 is positioned in theengagement hole 18 b, theexpandable engagement part 21 expands and theend part 24 and theengagement hole 18 b engage. Theexpandable engagement part 21 is fixed with respect to thegripping part 18 due to the engagement between saidend part 24 andengagement hole 18 b. When theend part 24 of saidexpandable engagement part 21 engages with theengagement hole 18 b, a configuration is realized so that thegripping part 15 b of the linear grippingmember 15 protrudes outwards from the openingpart 14 b of theretrieval puncture needle 14 and extends to spread to theinsertion puncture needle 13 side. - Moreover, the elastic member which acts as the advancement prevention means of the present invention is configured by the
coil spring 22, and the advancement side fixing means of the present invention are configured by theexpandable engagement part 21 and theengagement hole 18 b of thegripping part 18. Furthermore, theretrieval puncture needle 14 is inserted and held in the holdinghole 11 b of the upperpart holding tool 11 and the holdinghole 12 b of the lowerpart holding tool 12 in a state in which theopening part 14 b is oriented towards theinsertion puncture needle 13 side, and the upperpart holding tool 11 and the lowerpart holding tool 12 hold theretrieval puncture needle 14 in a state in which it is parallel with theinsertion puncture needle 13. Furthermore, the grippingparts suturing thread 16 is configured by a fine wire comprising resin material. - With this configuration and the use of the
medical suturing tool 10, when the abdominal wall and the gastric wall of the patient are sutured, for example, theexpandable engagement part 21 is first of all pulled upwards of thegripping part 18 by means of the elasticity of thecoil spring 22, and a state is achieved in which the upper part portion of theinsertion rod 15 a is made to protrude upwards of thegripping part 18. By virtue of this, the linear grippingmember 15 is pulled upwards and is positioned inside theinsertion hole 14 a of theretrieval puncture needle 14. In this state, themedical suturing tool 10 is pushed into the surface of the patient's skin in the abdomen part, and, as shown inFIG. 6 , theinsertion puncture needle 13 and theretrieval puncture needle 14 pierce the abdominal wall A and the gastric wall B. It should be noted that FIGS. 6 to 9 which are used for the description given below are drawings showing themedical suturing tool 10 schematically, and the sizes etc. of all the elements are different from those of themedical suturing tool 10 shown inFIGS. 1 and 2 . - In this case, the
insertion puncture needle 13 and theretrieval puncture needle 14 are pushed in until the lowerpart holding tool 12 reaches the surface of the skin of the abdominal wall A, and the openingparts gripping part 19 is pushed downwards to push the upper part portion of theinsertion rod 15 a inside theinsertion hole 14 a of theretrieval puncture needle 14. By virtue of this, thegripping part 15 b of the linear grippingmember 15 is sent outwards of theretrieval puncture needle 14 from the openingpart 14 b, it bends in a horizontal direction and also forks with a gap between the tip end parts, extending to theinsertion puncture needle 13 side, and the situation shown inFIG. 7 is achieved. - In this case, the
end part 24 of theexpandable engagement part 21 and theengagement hole part 18 b of thegripping part 18 engage, whereby theexpandable engagement part 21 is fixed with respect to thegripping part 18. Consequently, the linear grippingmember 15 is also immobilized and the situation shown inFIG. 7 is maintained. Next, as shown inFIGS. 1 and 8 , thesuturing thread 16 is inserted inside theinsertion hole 13 a of theinsertion puncture needle 13 from theguide hole 17 a of thegripping part 17. By virtue of this, the tip end part of thesuturing thread 16 advances downwards inside theinsertion hole 13 a, and extends outside and downwards from the openingpart 13 b. At this time the tip end part of thesuturing thread 16 enters between the fork of the extendedgripping part 15 b. - Next, the
end part 24 of theexpandable engagement part 21 is pushed inside thegripping part 18 and the engagement between theend part 24 and theengagement hole 18 b is released. At this time, the upper part portion of theinsertion rod 15 a is raised so as to protrude upwards of thegripping part 18 due to the elasticity of thecoil spring 22, and theinsertion rod 15 a together with thegripping part 15 b are also pulled upwards to achieve the situation shown inFIGS. 2 and 9 . At this time, thegripping part 15 b of the linear grippingmember 15 deforms so as to narrow the forked portion, keeping thesuturing thread 16 within said forked portion, and the tip end part of thesuturing thread 16 enters theinsertion hole 14 a of theretrieval puncture needle 14 in a state in which it is gripped by thegripping part 15 b. - Accordingly, in the situation in
FIG. 9 , a state is achieved in which the gastric wall B and the abdominal wall A are joined and both side portions of thesuturing thread 16 extend outside the patient's body, this being due to the fact that themedical suturing tool 10 is pulled out of the patient's body. The situation in shown inFIG. 10 is achieved by cutting so that both protruding side portions of saidsuturing thread 16 are a prescribed length. Then, both end parts of saidsuturing thread 16 are tied, whereby the situation ofFIG. 11 is reached and the suture is complete. It should be noted that the elastic force of thecoil spring 22 is set to be greater than the force by which the linear grippingmember 15 is pulled by thesuturing thread 16 when themedical suturing tool 10 is pulled out from the body of the patient. Consequently, when themedical suturing tool 10 is pulled out from the body of the patient, the linear grippingmember 15 is prevented from returning inside theinsertion hole 14 a of theretrieval puncture needle 14, and thesuturing thread 16 is held in an engaged state with thegripping part 15 b. As a result, stable suturing is possible. - As described above, with this
medical suturing tool 10 theinsertion rod 15 a on the base end part side of the linear grippingmember 15 is urged upwards by thecoil spring 22. Consequently, when thesuturing thread 16 is gripped by thegripping part 15 b and is pulled inside theinsertion hole 14 a of theretrieval puncture needle 14, theinsertion rod 15 a is pulled inside theinsertion hole 14 a and it is possible to prevent the grip on thesuturing thread 16 by thegripping part 15 b from being released. By virtue of this, it is possible to pull theretrieval puncture needle 14 and theinsertion puncture needle 13 out from the patient's body without manually handling the linear grippingmember 15 or thesuturing thread 16. - Furthermore, at that time the engagement between the
gripping part 15 b and thesuturing thread 16 is not readily released, and therefore the handling stability is improved. In addition, theexpandable engagement part 21 is provided on theinsertion rod 15 a and also theengagement hole 18 b which can engage with theend part 24 of theexpandable engagement part 21 is provided in thegripping part 18, and therefore it is possible to fix the position of thegripping part 15 b when thegripping part 15 b of the linear grippingmember 15 is protruding from the openingpart 14 b of theretrieval puncture needle 14. Consequently, this simplifies handling when the tip end part of thesuturing thread 16 is made to protrude from the openingpart 13 b of theinsertion puncture needle 13 to engage with thegripping part 15 b. In other words, there is no need to manually hold the grippingmember 19 back when thesuturing thread 16 is inserted inside theinsertion puncture needle 13. -
FIGS. 12 and 13 show amedical suturing tool 30 pertaining to the second mode of embodiment of the present invention. In thismedical suturing tool 30 the retreat side fixing member, acting as a retracting operating member and advancement prevention means which are linked to the upper end part of a linear grippingmember 35, is configured by a slidingengagement member 31, as shown inFIGS. 14 and 15 . Said slidingengagement member 31 is configured by alongitudinal rail part 32 which extends vertically, a slidingpart 33 which can slide vertically along therail part 32, and aninsertion tube 39 which is linked to the central lower end of therail part 32. - The inside of the
rail part 32 has the form of a frame which creates a space, and an annulargripping part 32 a is provided at the top end part. Then, anengagement part 34 with a roughly L-shaped cross section which protrudes forwards and then extends curving downwards is formed at the upper end part of therail part 32. It should be noted that an engagement protuberance is provided on the reverse side of a piece which extends downwards of theengagement part 34, although this is not shown in the figures. Furthermore, the slidingpart 33 is configured by an elliptical plate body which is longer in the lateral direction, andgripping hole parts engagement recess part 36 which can engage with (the engagement protuberance of) the engagement part 34 (this is referred to below simply as “theengagement part 34”) is formed in the central upper part on the front surface of the slidingpart 33. -
Said engagement part 34 andengagement recess part 36 engage when the slidingpart 33 is moved to the upper part of therail part 32, and the engagement is released from this state when the slidingpart 33 is moved to the lower part of therail part 32. Aninsertion tube 39 is configured from a tube body made of resin and the linear grippingmember 35 can be inserted therein. Then, the upper end part of aninsertion rod 35 a of the linear grippingmember 35 is linked to the lower end central part of the slidingpart 33. The linear grippingmember 35 moves inside theretrieval puncture needle 14 in accordance with the vertical movement of the slidingpart 33.FIGS. 14 and 15 show the state of such a linear grippingmember 35. - To expedite the description, it should be noted that
FIGS. 14 and 15 do not show theretrieval puncture needle 14, but, as shown inFIG. 14 , when the slidingpart 33 is moved to the lower part of therail part 32, the upper end part of theinsertion rod 35 a enters theretrieval puncture needle 14, and thegripping part 35 b protrudes from the tip end part of theretrieval puncture needle 14. By virtue of this, thegripping part 35 b spreads out. Furthermore, as shown inFIG. 15 , when the slidingpart 33 is moved to the upper part of therail part 32, the upper end side portion of theinsertion rod 35 a enters the inner side of the frame-shapedrail part 32, and most of the grippingmember 35 b retreats to enter theretrieval puncture needle 14. By virtue of this, thegripping part 35 b extends in a straight line. - Moreover, the retracting operating member pertaining to the present invention is configured by the sliding
part 33, and the retreat side fixing member which acts as the advancement prevention means pertaining to the present invention is configured by theengagement part 34 and theengagement recess part 36. Furthermore, themedical suturing tool 30 is not provided with advancement side fixing means. The configuration of the other components of saidmedical suturing tool 30 is the same as that of themedical suturing tool 10 described above. Accordingly identical components carry identical references, and a description thereof will be omitted. - Using the
medical suturing tool 30 configured in this way, when the abdominal wall A and the gastric wall B of the patient are sutured, the slidingpart 33 is firstly pulled up to the upper part of therail part 32, and theengagement part 34 and theengagement recess part 36 are set so as to be in an engaged state. By virtue of this, the linear grippingmember 35 is pulled upwards, and thegripping part 35 b is positioned inside theinsertion hole 14 a of theretrieval puncture needle 14.FIG. 15 shows the linear grippingmember 35 in this state. Next, in this state, themedical suturing tool 30 is pushed into the surface of the patient's skin in the abdomen part, and, as shown inFIG. 16 , theinsertion puncture needle 13 and theretrieval puncture needle 14 pierce the abdominal wall A and the gastric wall B. - It should be noted that FIGS. 16 to 19 which are used for the description given below are drawings showing the
medical suturing tool 30 schematically, and the sizes etc. of all the elements are different from those of themedical suturing tool 30 shown inFIGS. 12 and 13 . Next, the slidingpart 33 is moved downwards, and theinsertion rod 35 a of the linear grippingmember 35 is pushed inside theinsertion hole 14 a of theretrieval puncture needle 14. By virtue of this, thegripping part 35 b of the linear grippingmember 35 is sent outwards of theretrieval puncture needle 14 from the openingpart 14 b, and the situation shown inFIG. 17 is reached.FIG. 14 shows the linear grippingmember 35 in this state. It should be noted that inFIG. 14 the slidingengagement member 31 is shown as seen from the front, and the linear grippingmember 35 is shown seen from a direction that is different from that shown inFIG. 17 . - In this case, the sliding
part 33 reaches a state of immobilization with respect to therail part 32, due to friction force. Consequently, the linear grippingmember 35 is also immobilized, and the situation shown inFIG. 17 is maintained. Next, as shown inFIGS. 12 and 18 , thesuturing thread 16 is inserted inside theinsertion hole 13 a of theinsertion puncture needle 13 from theguide hole 17 a of thegripping part 17. By virtue of this, the tip end part of thesuturing thread 16 extends downwards to the outside from the openingpart 13 b, and enters within the fork of the extendedgripping part 35 b. - Next, the sliding
part 33 is moved upwards, and theengagement part 34 and theengagement recess part 36 engage to reach the situation inFIG. 19 . At this time, thegripping part 35 b of the linear grippingmember 35 deforms so as to narrow the forked portion, keeping thesuturing thread 16 within said forked portion, and the tip end part of thesuturing thread 16 enters theinsertion hole 14 a of theretrieval puncture needle 14 in a state in which it is engaged with thegripping part 35 b. In this case, thesuturing thread 16 is fixed in a state in which it is pushed into theopening part 14 b of theretrieval puncture needle 14 along with the tip end portion of thegripping part 35 b. Accordingly, in the situation inFIG. 19 , a state is achieved in which the gastric wall B and the abdominal wall A are joined and both side portions of thesuturing thread 16 extend outside the patient's body, this being due to the fact that themedical suturing tool 30 is pulled out of the patient's body. - The situation shown in
FIG. 10 is achieved by cutting so that both protruding side portions of saidsuturing thread 16 are a prescribed length, and in addition both end parts of saidsuturing thread 16 are tied, whereby the situation ofFIG. 11 is reached and the suture is complete. It should be noted that the engagement force of theengagement part 34 with theengagement recess part 36 is set to be greater than the force by which the linear grippingmember 35 is pulled by thesuturing thread 16 when themedical suturing tool 30 is pulled out from the body of the patient. Consequently, when themedical suturing tool 30 is pulled out from the body of the patient, the linear grippingmember 35 is prevented from returning inside theinsertion hole 14 a of theretrieval puncture needle 14, and thesuturing thread 16 is held in an engaged state with thegripping part 35 b. - In this way, with this
medical suturing tool 30 the advancement prevention means are configured by theengagement part 34 which is provided on therail part 32 and theengagement recess part 36 which is provided on the slidingpart 33, and therefore it is possible to reliably fix the slidingpart 33 and the linear grippingmember 35 by means of the engagement of theengagement part 34 with theengagement recess part 36. Furthermore, it is possible to allow the movement of the slidingpart 33 and the linear grippingmember 35 by releasing the engagement between theengagement part 34 and theengagement recess part 36. The other efficacious actions of thismedical suturing tool 30 are the same as for themedical suturing tool 10 described above. - Furthermore, the medical suturing tool pertaining to the present invention is not limited to the modes of embodiment described above, and appropriate modifications may be implemented. For example, with the
medical suturing tools parts insertion puncture needle 13 and theretrieval puncture needle 14 is not limited to the modes of embodiment described above either, and any kind of structure is possible provided that it is a structure which allows the engagement of thegripping part 15 b with thesuturing thread 16 outside the openingparts insertion puncture needle 13 and theretrieval puncture needle 14 are configured from stainless steel, but a resin material may also be used as the material for configuring them. - Furthermore, the upper
part holding tool 11 and the lowerpart holding tool 12 may be configured by members which are long in the longitudinal direction, instead of being plate-shaped. By means of this, the upperpart holding tool 11 and the lowerpart holding tool 12 are easier to hold manually, and they are easier to handle when a piercing is made. Furthermore, theinsertion puncture needle 13 and theretrieval puncture needle 14 are more strongly fixed to the holding tools. By virtue of this, when a piercing is made, it is possible to prevent the tip end parts of theinsertion puncture needle 13 and theretrieval puncture needle 14 turning or bending so as to extend with a gap between them. In addition, it is possible to configure the upperpart holding tool 11 and the lowerpart holding tool 12 as large components, and to provide a plurality of insertion puncture needles 13 and retrieval puncture needles 14. By virtue of this it is possible to carry out several suturing operations in a single turn, thereby reducing the time taken for the operation and improving efficiency. In addition, themedical suturing tools - Gripping
part 15 b may be formed in the shapes shown inFIGS. 20 and 21 . As shown, thegripping part 15 b compriseslinear coupling portions FIGS. 20 and 21 illustratelinear coupling portions FIG. 20 ,linear coupling portion 122 is composed of hanging-downportion 122 a that extends from the lower end ofbase portion 15 a (not shown in the figure) obliquely downward (in a direction away from linear coupling portion 123),inclined portion 122 b that extends from the lower end of hanging-downportion 122 a obliquely downward (in the direction parallel to linear coupling portion 123), and nearlyhorizontal portion 122 c that is bent from the tip portion ofinclined portion 122 b and extends slightly to the upper side (parallel tolinear coupling portion 123 in the plan view). - On the tip of nearly
horizontal portion 122 c, bendingportion 122 d extending nearly parallel to hanging-downportion 122 a in the plan view and towardlinear coupling portion 123 is formed. Also, as shown inFIG. 21 ,linear coupling portion 123 is composed of hanging-down portion 123 a that extends from the lower end (not shown in the figure) ofbase portion 15 a obliquely downward (in a direction away from linear coupling portion 122), inclined portion 123 b that is bent from the lower end of hanging-down portion 123 a and extends obliquely downward parallel toinclined portion 122 b, and nearlyhorizontal portion 123 c that is bent from the tip portion of inclined portion 123 b and extends in a nearly horizontal direction parallel to nearlyhorizontal portion 122 c. On the tip of nearlyhorizontal portion 123 c, bendingportion 123 d formed in a slender U-shape in the plan view is formed. - The operational relationship between gripping
portion 15 b and asuture 16 changes as shown inFIGS. 22 and 23 . As shown inFIGS. 22 and 23 , grippingportion 15 b andsuture 16 are coupled to each other and enter the interior ofinsertion hole 14 a ofpuncture needle 14.FIG. 22 is a diagram illustrating the state as seen from the front, andFIG. 23 shows the state as seen from the side. FIGS. 22(a) and 23(a) illustrate grippingportion 15 b andsuture 16 in the same state as that shown inFIG. 8 . Then, from the state shown in FIGS. 22(a) and 23(a), linear grippingmember 15 is pulled up slightly, and hanging-downportions 122 a, 123 a approach each other to become linear, and they enterpuncture needle 14. As a result, as shown in FIGS. 22(b) and 23(b),inclined portions 122 b, 123 b also approach each other and tightly contact each other, andsuture 16 is held between nearlyhorizontal portions - Then, linear gripping
member 15 is pulled up slightly, and inclinedportions 122 b, 123 b enterpuncture needle 14. As shown in FIGS. 22(c) and 23(c), nearlyhorizontal portions suture 16 is fastened. Then, linear grippingmember 15 is pulled up slightly, and the upper portions of nearlyhorizontal portions enter puncture needle 14. As a result, as shown in FIGS. 22(d) and 23(d), since nearlyhorizontal portions suture 16 is held by them. Then, linear grippingmember 15 is pulled up and the remaining portions of nearlyhorizontal portions enter puncture needle 14, so thatsuture 16 hits the edge portion of openingportion 14 b and is positioned on the lower side between nearlyhorizontal portions - In this state, said bending
portions suture 16 is coupled to the coupling portion of bendingportions member 15 is further pulled intopuncture needle 14, as shown in FIGS. 22(f) and 23(f), the entirety of grippingportion 15 b enterspuncture needle 14, and the portion of coupling betweensuture 16 and grippingportion 15 b goes together with grippingportion 15 b intopuncture needle 14. Said FIGS. 22(f) and 23(f) correspond toFIGS. 2 and 9 , respectively. Consequently, in the state shown inFIGS. 2 and 9 , when suturing unit formedical use 10 is pulled out of the body of the patient, the two side portions ofsuture 16 extend out of the body of the patient such that stomach wall B is bonded to stomach wall A. -
FIG. 24 is a diagram illustrating suturing unit formedical use 130 of a third embodiment of the present invention. Said suturing unit for medical use 1301 has oneinsertion puncture needle 113 of the same structure as that of saidpuncture needle 13, and tworetrieval piercing needles 114 having the same structure as that of saidpuncture needle 14. Also,upper holding unit 131 andlower holding unit 132 that hold said oneinsertion puncture needle 113 and two retrieval puncture needles 114 are formed in a rectangular shape with the major side in the left/right direction with respect to said upper holding unit 111 and lower holding unit 112. - On said
upper holding unit 131, three round holdingholes 131 a, 131 b, 131 c with a prescribed spacing between them are formed, and, onlower holding unit 132, round holdingholes 132 a, 132 b, 132 c are formed with the same spacing as that for said round holdingholes 131 a, 131 b, 131 c. Also, one of two retrieval puncture needles 14 is held toupper holding unit 131 andlower holding unit 132 via round holdingholes 131 a and 132 a,insertion puncture needle 13 is held via holdinghole 131 b and holding hole 132 b inupper holding unit 131 andlower holding unit 132. The orientation and position relationship between said onepuncture needle 14 andinsertion puncture needle 13 is the same as that in said Embodiment 1. - The other
retrieval puncture needle 114 is held via holding hole 131 c and holding hole 132 c in saidupper holding unit 131 andlower holding unit 132 havingopening portion 114 b facingopening portion 114 b of one of the otherretrieval puncture needle 114. Also, bendingportions linear coupling portions portion 133 are formed bent round to form a loop. The constitution of the remaining portion of said suturing unit formedical use 130 is the same as that of said suturing unit formedical use 10. Consequently, the same parts as those adopted in the above are adopted, and they will not be explained again. Also, the shape of the portion of holdingportion 133 other than bendingportions portion 15 b. However, the structure is shown only schematically inFIG. 24 andFIGS. 26, 27 , 29 and 30 to be used in the following explanation. - When suturing unit for
medical use 130 with said constitution is used to perform suturing for abdominal wall A and stomach wall B of a patient, the suturing operation is performed as shown inFIGS. 25-33 .FIGS. 25-31 to be used in the following explanation are schematic diagrams illustrating suturing unit formedical use 130. The sizes and shapes of the various portions are different from those of suturing unit formedical use 130 shown inFIG. 24 . In this case, first of all, due to the elasticity ofcoil spring 126, stretchingcoupling portion 125 is pushed up above holdingportion 118, and upper portions ofbase portions 15 a of lineargripping members 15 attached on the two retrieval puncture needles 14 protrude above holdingportion 118. - Here, suturing unit for
medical use 130 in this state is pressed into the surface of the skin in the abdominal portion of the patient, and, as shown inFIG. 25 ,puncture needle 13 and two puncture needles 14 are pierced into abdominal wall A and stomach wall B. Also, the operation in the state shown inFIGS. 25-38 is the same as that shown inFIGS. 6-9 . During this operation, holdingportion 133 andsuture 116 are coupled to each other while the state is changed as shown inFIGS. 22 and 23 . - As shown in
FIG. 28 , the tip portion ofsuture 116 inserted frompuncture needle 113 is coupled to grippingportion 133 of linear gripping member 115 inserted in one of puncture needles 114, and it enterspuncture needle 114. From this state, grippingportion 124 of theother puncture needle 114 is pressed down, so that the upper portion ofbase gripping portion 115 a is pressed into insertinghole 114 a ofpuncture needle 114. As a result, grippingportion 133exits opening portion 114 b to the exterior ofpuncture needle 114, and, while it is bent in the horizontal direction, it stretches to the sides ofpuncture needle 113 so that the spacing betweenlinear coupling portions FIG. 29 . - In this case,
end portion 125 a of stretchingcoupling portion 125 andcoupling hole 118 b of holdingportion 118 are coupled to each other, and stretchingcoupling portion 125 is fixed with respect to holdingportion 118. As a result, linear gripping member 115 is also in a stationary state, and the state shown inFIG. 29 is maintained. Then, as shown inFIG. 30 ,suture 116 is inserted in insertinghole 113 a of puncture needle forinsertion 113, and its tip portion protrudes below andoutside opening portion 113 b. As a result, the tip portion ofsuture 116 enters betweenlinear coupling portions portion 133 that has been expanded. - Then,
end portion 125 a of stretchingcoupling portion 125 is forced into holdingportion 118, and coupling betweenend portion 125 a andcoupling hole 118 b is released. Due to the elasticity ofcoil spring 126, the upper portion ofbase portion 115 a is protruded to above holdingportion 118. As a result, together withbase portion 115 a, grippingportion 133 is also pulled up to the state shown inFIG. 31 . In this case, for grippingportion 133, the spacing betweenlinear coupling portions suture 116. The tip portion ofsuture 116 is fixed in openingportion 114 b ofpuncture needle 114 while held by grippingportion 133, or it may enter insertinghole 114 a and be fixed in insertinghole 114 a. - Consequently, in the state shown in
FIG. 31 , by pulling suturing unit formedical use 130 out of the body of the patient, twosutures 116 extend out of the body of the patient for two side portions such that stomach wall B and abdominal wall A are bonded to each other. Then, by cutting the two protruding side portions of said twosutures 116 to a prescribed length, the state becomes as shown inFIG. 32 . In addition, by tying the two end portions ofsutures 116, respectively, suturing comes to an end in the state shown inFIG. 33 . - As a result, in a single round of operation, two
sutures 116 can be used in suturing. Consequently, the suturing operation is simplified, and the operation time is decreased. Especially, when the suturing portion is large, the operation can be performed at high efficiency. Also, because bendingportions linear coupling portions medical use 130 are the same as those of said suturing unit formedical use 10. -
FIGS. 34-37 illustrate the state of the suturing operation using suturing unit formedical use 140 inEmbodiment 4 of the present invention. Said suturing unit formedical use 140 has two insertion puncture needles 113 having the same structure as that of thepuncture needle 113 of the third embodiment, and oneretrieval puncture needle 144. Also, as the upper holding unit and lower holding unit for holding said twopuncture needles 113 and onepuncture needle 144, the same structures as those ofupper holding unit 131 andlower holding unit 132 of Embodiment 3 are used. At the central portion between upper holdingunit 131 andlower holding unit 132,puncture needle 144 is attached, and, on the two side portions ofupper holding unit 131 andlower holding unit 132, puncture needles 113 are attached with a prescribed spacing frompuncture needle 144. - Also, linear coupling portions 142, 143 that form holding
portion 141 of linear holdingmember 145 are formed such that after spreading to an obtuse angle, bending occurs such that their tips approach each other, and bendingportions medical use 140, instead of holdingportion 124,slide engagement member 146 is used, similar to slideengagement member 31. Thisslide engagement member 146 is composed oflongitudinal rail portion 147 extending in the upper/lower direction, andslide portion 148 that can slide up/down alongrail portion 147. - Said
rail portion 147 is formed in a frame shape with a space formed in its interior, and, on its upper end portion, ring-shapedholding portion 147 a is set. Also,slide portion 148 is formed as an elliptic plate member that has its major axis in the left/right direction, withhole portions rail portion 147, and at the center of the upper portion ofslide portion 148, a coupled portion that can be coupled to the coupling portion ofrail portion 147 is formed. This coupling portion and coupled portion are coupled to each other whenslide portion 148 is driven to move to the upper end ofrail portion 147. From this state, the coupling is released whenslide portion 148 moves to the lower end ofrail portion 147. - The upper end portion of base portion 145 a of linear gripping
member 145 is connected to the central portion of the lower end ofslide portion 148, and, when saidslide portion 148 moves up/down, linear grippingmember 145 moves insidepuncture needle 144. That is, as shown inFIGS. 35 and 36 , whenslide portion 148 moves to the lower end ofrail portion 147, the upper portion of base portion 145 a of linear grippingmember 145 enterspuncture needle 144, and grippingportion 141 protrudes and spreads from the tip opening ofpuncture needle 144. - Also, as shown in
FIGS. 34 and 37 , whenslide portion 148 is driven to move to the upper end ofrail portion 147, the upper end portion of base portion 145 a of linear grippingmember 145 enters the inner side in the frame shape ofrail portion 147, and grippingportion 141 retreats and enterspuncture needle 144. The constitution of the remaining portion of suturing unit formedical use 140 is the same as that of said suturing unit formedical use 10. As a result, they will not be explained again. - When suturing unit for
medical use 140 with said constitution is used to suture abdominal wall A and stomach wall B of the patient, first of all,slide portion 148 is pulled to the upper end ofrail portion 147, and the coupling portion and the coupled portion are coupled to each other. As a result, linear grippingmember 145 is pulled upward, and grippingportion 141 is positioned inpuncture needle 144. Then, suturing unit formedical use 140 in this state is pressed into the skin surface of the abdominal portion of the patient, and, as shown inFIG. 34 , twopuncture needles 113 and onepuncture needle 144 pierce abdominal wall A and stomach wall B. Then, whenslide portion 148 is driven to move downward, base portion 145 a of linear grippingmember 145 is pressed intopuncture needle 144. As a result, grippingportion 141 of linear grippingmember 145 exitspuncture needle 144 from openingportion 114 b to obtain the state shown inFIG. 35 . - In this case, due to frictional force,
slide portion 148 becomes stationary with respect torail portion 147. As a result, linear grippingmember 145 is also stationary, and the state shown inFIG. 35 is maintained. Then, as shown inFIG. 36 ,sutures 116 are inserted into puncture needles 113 from guide holes 117 a of holdingportions 117 of two puncture needles 113. As a result, the tip portions of twosutures 116 extend below and outside openingportions 113 b, and they enter expandedgripping portion 141. Then,slide portion 148 is driven to move upward, and the coupling portion and coupled portion are coupled to each other to obtain the state shown inFIG. 37 . - In this case, gripping
portion 141 of linear grippingmember 145 is deformed such that the spacing between linear coupling portions 142, 143 decreases to hold bothsutures 116. The tip portions of said bothsutures 116enter puncture needle 144 while they are coupled to grippingportion 141. In this case, bothsutures 116 are coupled to bendingportions FIG. 37 , by pulling suturing unit formedical use 140 from the body of the patient, bothsutures 116 extend out from the patient for both side portions such that stomach wall B is bonded to stomach wall A. - The two protruding side portions of said two
sutures 116 are cut at a prescribed length, and the state becomes the same as inFIG. 32 . In addition, by tying the two end portions of twosutures 116, the state becomes as shown inFIG. 33 , and suturing comes to an end. By means of said suturing unit formedical use 140, suturing can be performed for twosutures 116 simultaneously. As a result, the suturing operation can be performed in a simple way, and, at the same time, the operation time can be further shortened. The remaining functions of suturing unit formedical use 140 are the same as those of said suturing unit formedical use 10. - As can be seen from the above description, at least one embodiment of the present invention is a device that aims to provide a medical suturing tool which is easily handled and which offers improved stability of suturing. In order to achieve the aim, the features the configuration of the medical suturing tool pertaining to at least one embodiment of the present invention lie in the fact that it is a medical suturing tool in which a linear gripping member is inserted from the base end part side of an insertion hole in a retrieval puncture needle, and a gripping part at the tip end of the linear gripping member is made to protrude from an opening part which is formed at the tip end of the retrieval puncture needle; also, a suturing thread is inserted from the base end part side of an insertion hole in an insertion puncture needle which is arranged approximately parallel and held with a prescribed space between it and the retrieval puncture needle, and, in a state in which the tip end part of the suturing thread is made to protrude from the opening part formed at the tip end of the insertion puncture needle to extend to the gripping part side of the linear gripping member, the suturing thread can be gripped by the gripping part by causing the gripping part of the linear gripping member to retreat to the base end part side of the retrieval puncture needle; in said medical suturing tool a retracting operating member is linked to the base end side of the linear gripping member, the retracting operating member is retractably attached to the base end part side of the retrieval puncture needle, and also provision is made for advancement prevention means for preventing the advance of the retracting operating member with respect to the retrieval puncture needle when the retracting operating member is made to retreat, causing the gripping part of the linear gripping member to retreat to the base end part side of the retrieval puncture needle.
- The medical suturing tool pertaining to at least one embodiment of the present invention configured in the manner described above is provided with the retracting operating member which is joined to the base end side of the linear gripping member, and the advancement prevention means for preventing the advance of the retracting operating member from a retreated position. Then, the gripping part of the linear gripping member can retract from the opening which is formed at the tip end of the retrieval puncture needle due to the fact that the retracting operating member is made to retract. Furthermore, when the retracting operating member is made to retreat, causing the retreat of the gripping part of the linear gripping member to the base end part side inside the retrieval puncture needle, the retracting operating member cannot advance with respect to the retrieval puncture needle due to the advancement prevention means.
- In other words, the time when said retracting operating member is made to retreat, causing the retreat of the gripping part of the linear gripping member to the base end part side inside the retrieval puncture needle constitutes the time when the suturing thread is gripped by the gripping part or when the suturing thread is gripped by the gripping part and pulled inside the retrieval puncture needle, and it is therefore possible to prevent the release of the grip (engagement) of the suturing thread by virtue of the gripping part due to the fact that the advance of the retracting operating member towards the inside of the retrieval puncture needle is prevented. By virtue of this, it is possible to pull the retrieval puncture needle and the insertion puncture needle out from the patient's body without in particular manually handling the linear gripping member or the suturing thread. Furthermore, the engagement of the gripping part of the linear gripping member and the suturing thread is not readily released, and therefore the stability of the suturing operation is improved.
- Moreover, the advance of the retracting operating member in this case involves the movement of the linear gripping member to inside the patient's body in a state in which the medical suturing tool has pierced the patient's body, and the retreat of the retracting operating member involves the movement of the linear gripping member to outside the patient's body. Furthermore, the advancement prevention means are configured by urging means for urging the retracting operating member to the side of retreat, and engagement means or the like provided with release means, and when the retracting operating member is moved to the side of advance, forwards movement is possible by means of a prescribed method and according to the intentions of the operator.
- Another feature of the configuration of the medical suturing tool pertaining to at least one embodiment of the present invention lies in the fact that the advancement prevention means are configured by an elastic member which urges the retracting operating member towards the outer part of the base end side of the retrieval puncture needle. By virtue of this it is possible to configure the advancement prevention means with a simple member. Furthermore, the operator sets the degree of elasticity of the elastic member in this case so that it is possible to move the retracting operating member forwards in resistance to the elasticity of the elastic member, and, moreover, so that it is possible to prevent the retracting operating member from advancing due to the pull of the suturing thread when the retrieval puncture needle and the insertion puncture needle are pulled out from the patient's body. Furthermore, it is possible to use a coil spring or cord-shaped rubber etc. for the elastic member in this case.
- Another feature of the configuration of the medical suturing tool pertaining to at least one embodiment of the present invention lies in the fact that the advancement prevention means are configured by a retreat side fixing member which fixes the retracting operating member. It is possible to use as the retreat side fixing member in this case a member with which the retracting operating member can be fixed by means of the engagement between an engagement part and a part to be engaged, and furthermore with which the retracting operating member is able to move by means of the release of the engagement between said engagement part and part to be engaged. By virtue of this, it is possible to more reliably prevent the movement of the retracting operating member to the side of advance.
- Another feature of the configuration of the medical suturing tool pertaining to at least one embodiment of the present invention lies in the fact that provision is made for advancement side fixing means for fixing the retracting operating member with respect to the retrieval puncture needle when the retracting operating member is made to advance, causing the gripping part of the linear gripping member to protrude from the opening part in the retrieval puncture needle. By virtue of this it is possible to fix the position of the gripping part when the gripping part of the linear gripping member is protruding from the opening part of the retrieval puncture needle, and therefore this simplifies handling when the tip end part of the suturing thread is protruding from the opening part which is formed at the tip end of the insertion puncture needle and engaging with the gripping part of the linear gripping member. In other words, there is no need to manually hold the retracting operating member back when the suturing thread is inserted inside the insertion puncture needle.
